Switch Accessories
Switch accessories are parts added to molded case circuit breakers, open-type circuit breakers and motor protection circuit breakers to complete the device's connection, control and mechanical equipment. They are used to connect the switch to the busbar or cable, to operate it from the panel door, to trip it remotely, to adapt it for plug-in or withdrawable use and to cover live terminals. For the ABB Tmax XT and Emax 2, Siemens 3VA, 3VM, 3WA and 3WT, and Schneider Electric NSX families, connection terminals, terminal shields, handles and shafts, undervoltage and closing coils, fixed parts and plug-in socket kits are listed. Choose the accessory first by the switch's brand, series and frame size, then by the number of poles and, for coils, the control voltage; match the compatibility value in the product information, such as XT2, XT4 or NSX400/630, with your switch. There are also separate categories on the site for auxiliary contacts and shunt trip coils. Among switch accessories, an undervoltage coil must not be confused with a shunt trip coil: the former trips the switch when the voltage drops or is lost, the latter when voltage is applied.

How to choose Switch Accessories
Switch accessories are parts added to molded case circuit breakers, open-type circuit breakers and motor protection circuit breakers to complete the device's connection, control and mechanical equipment. They are used to connect the switch to the busbar or cable, to operate it from the panel door, to trip it remotely, to adapt it for plug-in or withdrawable use and to cover live terminals.
- Separate overcurrent/leakage protection, motor starting and local isolation requirements.
- Select rated current, pole count and breaking capacity (kA) from the installation calculation.
- Match coil voltage, auxiliary contacts and tripping curve to the control circuit and load type.
