MCCB shunt trip release specifications
W9 Group lists this MCCB shunt trip release for electrically commanded remote tripping of a compatible circuit breaker. Specify the host frame, control-supply version and wiring arrangement. A shunt release provides a trip command rather than remote closing or automatic fault detection by itself.

호스트 브레이커 식별하기
Provide the full MCCB model, frame and existing accessory arrangement. Confirm mechanical and electrical compatibility before ordering.
Specify the required function
Describe the operating or signaling task and the intended control system. Confirm the accessory function and any additional components.
Match the connection details
Request the exact wiring or installation drawing, mounting dimensions and terminal arrangement for the offered accessory.
Confirm the order contents
Confirm included parts, operating conditions and required documentation. Do not infer a complete control assembly from an accessory name.

구매자 FAQ
Shunt trip coil duty and breaker compatibility FAQs
Find answers about MCCB shunt release selection, configuration and ordering.
How does a shunt trip release work?
An external electrical command operates the release to trip a compatible breaker. Confirm the required supply, command duration and host mechanism for the offered accessory.
Is shunt trip the same as undervoltage release?
No. Shunt trip responds to an applied trip command, while undervoltage release has a different supply-loss response. Confirm which operating principle the control system requires.
Which frame codes are listed?
The original table lists SHT-125, SHT-250 and SHT-400 with their frame associations. Confirm the exact host model and mounting compatibility rather than selecting from current alone.
Can the coil remain energized continuously?
Confirm the exact duty cycle and pulse or continuous-duty design for the selected version. The source wording and timing notation are not sufficient to establish a universal energization duration.
How should a low-voltage DC control cable be sized?
Use the exact control-supply and wiring schedule, accounting for conductor length and voltage drop. The original table contains a DC24V cable-length schedule; confirm its conditions before applying it.
Does a shunt release detect residual current or reclose the breaker?
Neither function is established by the release alone. Confirm any external fault detector, controller, reset sequence and separate motor operator required by the system.
