Capacitor duty contactor- MO C

Our range of capacitor duty Contactors is specially designed for capacitor switching applications. As capacitor switching is associated with high inrush current, the contactors are provided with damping resistors which limit the value of inrush current to a safe value. The contactors are used in APFC panels for switching power capacitors. Selection of these capacitors depends on the amount of reactive power compensation required.

Features

• Separately terminated de-latching contacts for enhanced operational reliability
• Improved switching performance
• Dual contact gap for auxiliary contacts
• Separate termination of damping resistors
• Encapsulated resistor assembly
• Wide and chatter-free operating band
• Higher electrical life
• Enhanced product safety

MCX four pole contactors

• Ratings: 16 A to 800 A AC-1 duty
• Suitable for supply changeover and genset applications
• Available in five frame sizes and nineteen current ratings
• Alpha-numeric terminal marking
• Wide operating band up to 100 A AC-1

UA30..RA 3-pole contactors for capacitor switching, can be used in installations in which the peak current far exceeds 100 times nominal rms current. The contactors are delivered complete with their damping resistors and must be used without additional inductances (see table below). The capacitors must be discharged (maximum residual voltage at terminals ≤ 50 V) before being re-energized when the contactors are making. Their electrical durability is 250 000 operating cycles for Ue < 500 V and 100 000 operating cycles for 500 V ≤ Ue ≤ 690 V. The UA..RA contactors are fitted with a special front mounted block, which ensures the serial insertion of 3 damping resistors into the circuit to limit the current peak on energization of the capacitor bank. Their connection also ensures capacitor precharging in order to limit the second current peak occurring upon making of the main poles. The insertion of resistors allows to damp the highest current peak of the capacitor when switching on, whatever its level. The UA..RA series 3-pole contactors are of the block type design. - Main poles and auxiliary contacts: 3 main poles, 1 built-in auxiliary contact - Control circuit: AC operated with laminated magnet circuit - Accessories: a wide range of accessories is available.

A "TC add-on block" typically refers to an auxiliary contact block designed to be added to a power contactor, such as those in the TC (TeSys Compact) series by Schneider Electric. These blocks expand the functionality of the contactor by adding extra normally open (NO) or normally closed (NC) contacts. They are commonly used for signaling, feedback, or controlling other devices based on the state of the main contactor.
