OUVT-1 Over-under Voltage Release

The OUVT-1 Over-under Voltage Release is a fundamental accessory designed to automatically trip a connected circuit breaker when electrical system voltage exceeds a pre-set overvoltage threshold or drops below an undervoltage limit. This precise voltage-dependent tripping ensures critical protection for sensitive equipment against damaging fluctuations, safeguarding system integrity. With adjustable trip settings and delay times, the OUVT-1 provides an integral solution for enhancing safety and stability across residential, commercial, and industrial applications.

FAQs

What is the primary function of the OUVT-1 Over/Under Voltage Release?

The OUVT-1 automatically trips the circuit breaker when voltage levels rise above or drop below safe limits, preventing equipment damage due to overvoltage or undervoltage conditions.

Which circuit breakers can the OUVT-1 be used with?

It is specifically designed for CHINT NB1-63 series circuit breakers, offering seamless assembly and consistent performance.

How does it respond to voltage fluctuations?

The OUVT-1 trips the breaker if the voltage falls below 35% of the rated value or exceeds 105% of the overvoltage setting, ensuring rapid disconnection under abnormal voltage conditions.

What is its lifespan and reliability?

The device is rated for over 4000 mechanical and electrical operations, including repeated overvoltage and undervoltage trips, ensuring dependable long-term operation.

Is installation straightforward?

Yes. Simply remove the left cover of the NB1-63 breaker, attach the OUVT-1 module, and mount it on a TH35-7.5 steel DIN rail — no special tools or rewiring required.
