RECB, Type B self-reclosing RCCB

Product catalog summary

Introduction
The document discusses the Type B self-reclosing RCCB (Residual Current Circuit Breaker) by Circutor, highlighting its importance in providing comprehensive earth leakage protection against AC, DC, and AC/DC currents. This protection is crucial for modern electrical systems that incorporate power electronics, such as variable speed drives, UPS systems, and electric vehicle chargers.

Why Use Type B Earth Leakage Protection?
Type B protection is essential because it detects continuous residual currents, unlike Type A and AC devices. These currents are prevalent in systems with power electronics, and failure to detect them can compromise safety and service continuity.

Product Features
The RECB is a 4-pole circuit breaker with a smart reclosing motor, allowing automatic and safe reclosure in three attempts. It is compact, modular, and easy to install, requiring no additional wiring. Key features include:

Plug & Play installation
Fixed sequence and fast status control
Space-saving design
Front mechanism for ON/OFF, resetting, and locking
LED indicators and test button

Reclosing System
The RECB features a timed reclosing system that attempts to reclose up to three times after specific standby periods (3, 20, and 180 seconds), ensuring maximum service continuity without compromising safety. It includes a lockout feature to override reclosing manually.

Applications
The RECB is suitable for installations requiring continuous electrical service, such as industrial sectors, telecommunications, data centers, electric vehicle charging points, and photovoltaic installations.

Technical Specifications
Key specifications include:

Sensitivity: 30 or 300 mA
Trip delay: Instantaneous
Nominal current: 40 or 63 A
Number of poles: 4
Operating voltage: 230/400 V AC
Operating temperature: -25 to +55 ºC

Conclusion
The RECB by Circutor offers a reliable solution for ensuring electrical safety and service continuity in modern installations with power electronics. Its compact design and advanced features make it a versatile choice for various applications.

Why use type B earth leakage protection? In recent years the use of loads with power electronics has become widespread. Type B earth leakage protection is the only protection that safeguards people and loads against AC, DC and AC/DC leakage. Type A and AC earth leakage protection devices do not detect continuous residual currents, which are so common in loads from variable speed drives, UPS's, EV chargers, photovoltaic installations, etc. AC type protection Sinusoidal alternating current Type A protection Sinusoidal alternating current Pulsating alternating current Type B protection Sinusoidal...
