Product FAQs
6 answersWhat type of ground fault protection does the M9R81425 provide?
The M9R81425 is a Multi9 GFP Residual Current Circuit Breaker (RCCB) featuring Type A-SI (Super Immunized) earth-leakage protection. This class is specifically designed to prevent nuisance tripping in environments with high electrical noise or harmonics.
What is the earth-leakage sensitivity rating for this Multi9 RCCB?
It features an instantaneous earth-leakage sensitivity of 26 mA under UL 1053 standards, and 30 mA under EN/IEC 61008-1 standards, providing rapid equipment protection against ground faults.
How much DIN rail space does this 4-pole breaker require?
The breaker mounts on a standard 35mm DIN rail and occupies 72 mm of width, which is equivalent to eight 9 mm pitches in a control panel.
Does this breaker provide local trip indication?
Yes, the front face includes a contact position indicator with local signaling for ON, OFF, and fault trip states. This allows electricians to quickly identify if a ground fault caused the circuit to open.
What type of terminals are used for wire connections on the M9R81425?
This RCCB is equipped with tunnel terminals for secure wire termination.
Can this breaker be used on both 50 Hz and 60 Hz systems?
Yes, the M9R81425 is rated for operation on both 50 Hz and 60 Hz AC networks, making it suitable for a variety of industrial applications.
