Weidmüller maxGUARD resettable circuit breaker terminals

Friday, 29 May, 2020 | Supplied by: Weidmuller Pty Ltd

The maxGUARD series of resettable electronic circuit breaker terminals is a modular system that combines both electronic overload protection and 24 VDC distribution in the one terminal.

maxGUARD overcomes the limitations of 24 VDC switchmode power supplies, such as foldback or loss of supply under short circuit or high inrush conditions. The current-sensing feature enables overload trips and instant trip of the breaker under short circuit, allowing isolation of faults on a 24 VDC control system without losing the 24 V supply.

With maxGUARD, the terminal blocks previously installed separately for 24 VDC distribution are now integrated with the electronic circuit breaker module. This saves considerable time during installation and reduces the overall amount of space required on the terminal rail by up to 50%.

Available in single-slice modules with a 6 mm width, they can be arranged to custom requirements with either fixed or adjustable current modules from 1 to 12 A. Assembly is as simple as installing terminals on a rail. Users connect the modules together with standard Weidmüller coloured plug-in cross-connection combs.

Two control module options offer additional functions of remote reset, system trip indication, 90% alarm and system shutdown. Conformal-coated variants are also available for harsh environments and corrosive atmospheres.

The series now also has approvals for Marine, Class 2 (North America) and Ex areas, and offers integrated test points for easy maintenance and troubleshooting.
