ABB SWITCHGEAR

Capacitor switching application leads to very high current peak at capacitor energization. UA..RA contactors are designed with damping resistor to handle current peaks without limitation.

Product benefits

• Widest contactor range on the market up to 80 Kvar
• Reliable in capacitor switching demanding application
• Easy selection with CAPCAL software.

ABB 3-pole / 4pole contactors offer an exhaustive selection of products for simple and extreme applications as well as products with specific purposes.The AF contactor technology revolutionizes how we use contactors and allows use in all parts of the world and in all network conditions. Furthermore, mini-contactor range offers compact dimensions and specific connection possibilities. The AS contactor is efficient and allows you to optimize your equipment design. You can choose terminals between screw, push-in spring and ring tongue through our ranges. So whatever your need of a contactor might be, ABB will have a variant meeting just that.

Miniature Circuit Breakers (MCBs) ensure electrical safety in homes, offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short-circuits. Once a fault is detected, the MCB automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

For 100 years, we have continued to innovate MCBs and expand our product line to meet the demands of various applications and markets. Our products are compliant with global product standards such as IEC, UL and CSA. This established and certified portfolio is designed to provide maximum safety for buildings, assets and infrastructure.

Manual motor starters, also known as motor protection circuit breakers (MPCBs) or manual motor protectors (MMPs), are electromechanical protection devices for the main circuit. They are mainly used to switch motors ON/OFF manually and to provide fuseless protection against short-circuit, overload and phase failures. Fuseless protection saves costs, space and ensures a quick reaction under short-circuit condition by switching the motor off within milliseconds. Starter combinations are setup together with contactors and are available with screw or Push-in Spring terminals.

DRAS is a compact ergonomic enclosed direct-on-line starter. It’s the ideal solution for motor starting up to 7,5 kW. T16 thermal overload relays for motor protection should be selected separately according to motor’s nominal current.
