Type Residual Current Device Miniature Circuit Breaker
Features
True IP2X finger-safe design (front)
For applications in which AC and
pulsating DC fault currents are likely to
appear, nonselective and non-delayed
Designed to prevent unwanted tripping
caused by switching electronic circuit
devices
Auxiliary and Signal contacts may be
added
True IP2X finger-safe design (front)
Energy Limiting Design protects
downstream components better than
conventional breakers during short
circuits
Field mountable options for selective
applications
AC and DC voltage ratings in one
convenient device
Superior shock and vibration resistance
