CHINT SHT-X1 Shunt Release for NXB-63 / NXB-40 MCB Accessories

Brand Name: CHINT
Product Type: Shunt Release
Model: SHT-X1
Compatible Series: NXB-63 and NXB-40
Application: Low-voltage breaker accessory for panel and distribution systems
Category: Chint MCB

What is Chint Shunt Release?

The CHINT SHT-X1 Shunt Release for NXB-63 / NXB-40 MCB Accessories is a shunt trip release - an electrical accessory that mounts on MCBs (Miniature Circuit Breakers) to enable remote tripping. When control voltage (230V / 400V) is applied, the shunt release instantly trips the MCB, disconnecting the circuit.

Common Applications

  • Emergency Stop - Central emergency shutdown of multiple circuits
  • Fire Safety Systems - Interface with fire alarm to cut non-essential power
  • Remote Control - Switch off circuits from control room
  • Automation Integration - Controlled by BMS or PLC systems
  • Alarm Integration - Trip on security/intrusion alarms

How It Works

The shunt release contains an electromagnet coil. When energized with control voltage, the coil creates a magnetic field that mechanically trips the MCB's operating mechanism. The MCB latches in the OFF position until manually reset.

Technical Specifications

ModelChint
Control Voltage230V / 400V
CompatibilityChint NXB, NB1, NBH8 series MCBs
MountingLeft side mounting on MCB
OperationInstant trip on voltage application

Installation Note

The Chint mounts on the left side of compatible MCBs. It requires a control voltage source (separate from the protected circuit). For emergency stop applications, use normally-open push buttons in series with the control voltage supply.
