TA Boxall Engineering Control and automation machines

As authorised agents of leading automation manufacturers, we can bring you the following top quality products at inexpensive prices.

Switches

We have 30 mm plastic pushbuttons, switches and pilot lights from Schneider Electric and Crompton Controls. Our combination of electrical disconnect switches, fuses or circuit breakers is not only effective in controlling, protecting and separating electrical equipment but are guaranteed to last.

Switchgears are used to de-energise equipment to allow work to be carried out and to resolve issues downstream. We have the following:
Biased switches
A switch usually maintains its set position once it has been operated. A biased switch contains a mechanism that springs it into a different position when an operator releases it. Some push-button switches, like the momentary, are a type of biased switch.

Our push-to-make switch is one of the most commonly used. It works by making contact when the button is pressed and breaking it when it is released. A push-to-break, on the other hand, is designed to break contact when the button is pushed.

Selector switch

The standard is IP69K and it always has integrated illumination option. They come in a range of different colours and the switch position is obvious, even from afar. With our range of switch configurators, you can choose the appropriate selector switch by intuition.

The enclosures and labelling can be combined to match particular application requirements, as well as, graphics-based component selection with a drag and drop feature. We also provide a section to preview, so this makes it easier for you to select the item you need.

Other switch features available include:

  • Pilot light (incandescent, LED)
  • Wobble sticks
  • Combined contact and signalling functions
  • Push buttons
  • Emergency stop or switch off mushroom head pushbuttons

Strength and safety

  • Meets standards of UL, IEC, EN, NOM and CSA standards
  • Full-power LED lights for visibility
  • IP 66, NEMA 4-rated (resilient sealing to resist oil and water corrosion)

Simplicity and speedy installation

  • Common accessories
  • Self-grounding operators are automatic and don’t need additional wiring
  • Block setting with one crew
  • Coloured contacts make the function easy to identify

A key benefit is our switches have been designed for industry, thereby making is tough and resistant to corrosion.

TA Boxall Engineering supplies quality switches to petrochemical plants, metallurgic companies, mining firms, wastewater treatment plants and automotive factories.

Relays

Relays are electromechanical switches that can be activated by an electrical signal instead of manually opening or closing a switch. Throughout the history of electronics, relays have featured prominently, particularly in the growth of the telegraph network.

There are various types of standard relay configurations, but it eventually boils down to poles and throws. In a relay system, the pole is a switch, and the throw is a possible connection.

The most basic type of relay is a single pole single throw (SPST), which has a dual port, A and B. A single pole signifies a single switch, also indicating that there is only one possible connection (A–> B). When the SPST is switched off, A is disconnected electrically from B.

A standard SPDT (single pole double throw) relay has three ports; A, B and C. In the off position, the SPDT relay may connect A and B, while A and C may be connected in the on position. In an electromagnetic relay, an electric current is used to activate the relay. The current generates a magnetic field that moves the relay’s armature which is used to make or break a connection. A high-power relay uses a double-break design which opens connections in two points. On the other hand, smaller relays are mainly single-break designs.

Benefits

Besides its efficient design, TA Boxall Engineering contactors provide a fast and easy set-up while preserving the small size of 45 and 55 mm (40 to 65 A). It also adheres strictly to international specifications.

The 40 to 65 A models have EverLink. This terminal technology guarantees a steadfast fastening even when there is a conductor creep.

Application

Applications for contactors include industry, large buildings, and infrastructure. They can be used to develop motor starters for certain applications.

Our contactors are designed for direct incorporation into control systems, and can also be used to power controls and signal equipment.

DC injections

DC injections are used to slow AC electric motors. In industry, they are applied by injecting a DC voltage into the AC motor winding after disconnecting the AC voltage, thereby applying a braking force to the rotor.

Application of DC injection braking

When power is disconnected from the motor, the rotor spins on its own for a while until the resulting friction brings it to a stop. Massive rotors and loads with a high moment of inertia, take a considerable amount of time to stop rotating through friction alone. To reduce downtime, or probably as a safety measure, DC injection can be used to halt the rotation.

At TA Boxall Engineering, we have a range of low-loss high-performance DC injectors, designed for use when DC power needs to be coupled with an RF coaxial transmission line. Contact our support team for more details.

Product collection and delivery for monitoring and diagnosis

If you have issues with your control gear, such as switching, relays, contactors of DC injectors, our company operates a product collection and delivery service. We will conduct a series of tests to monitor and identify the fault before repairing it.

We can cross-reference outdated parts and machines, either making “new for old” or finding replacements. We can also contact different manufacturers.
