Shunt Trip Release

This shunt trip release is a safety line for unexpected events. Buttons can stick, and operators can make mistakes. We know this from 42 years of experience. That is why we built this product differently. Unlike standard models that can burn out with long power-on time, our patented design (ZL201320072566.6) works steadily under continuous power. It solves a common problem. When used with the 4NO 4NC auxiliary switch on DW45 breakers, this shunt trip release stays safe even if the button is held too long. This gives you unmatched fault tolerance for your project.

We prove reliability with data. In our lab, every shunt trip release passes strict tests. This includes 10,000 operation tests at 80℃. Its pulse group immunity reaches ≥4KV. This means it works well even in areas with high electromagnetic noise. It gives you a steady tripping force of ≥20N within a 7.5-9mm stroke. This ensures a clean break every time. We test every unit before it leaves our factory. We provide detailed inspection records. This is the "quality first" principle we have followed since 1984.

This shunt trip release is used in distribution cabinets and industrial control panels. It is perfect for places that need a reliable emergency break system. Our after-sales team is backed by our technical department. We offer 24/7 support. If you have a problem, we act fast. We provide repair or replacement within the 18-month warranty period. For large projects, we can arrange on-site guidance and free operator training. A common question we get is, "What voltages are available?" We offer AC/DC 110V, 220V, and 380V as standard. Other voltages can be customized. The minimum order is just 1 piece.
