Product FAQs
8 answersWhat is the ground fault sensitivity rating for the M9R12463 RCCB?
This Multi9 GFP residual current circuit breaker has an earth leakage sensitivity of 86mA under UL 1053 standards and 100mA under IEC 61008-1 standards.
What type of residual current protection does the M9R12463 provide?
It features Type A-SI (Super Immunized) protection. This class is designed to handle AC and pulsating DC residual currents while resisting nuisance tripping from transient surges in industrial environments.
What wire sizes are compatible with the tunnel terminals on the M9R12463?
The terminals accept 18 AWG to 2 AWG rigid copper wire, or 18 AWG to 3 AWG flexible copper wire.
What is the recommended tightening torque for the terminal connections?
The top and bottom tunnel terminals should be torqued to 30.98 lb-in (3.5 N.m).
How much insulation should be stripped from the wire before terminating?
The recommended wire stripping length for the top and bottom connections is 0.55 inches (14 mm).
How much DIN rail space does this 4-pole RCCB require?
The M9R12463 occupies 4 standard 18mm modules, requiring a total width of 72mm (2.83 inches) on a 35mm DIN rail.
Can auxiliary contacts or shunt trips be added to the M9R12463?
Yes, it is compatible with select Multi9 electrical auxiliaries, including the 26923 auxiliary contact and M9A26478 shunt trip release.
Does the M9R12463 provide overcurrent and short-circuit protection?
No, this is a Residual Current Circuit Breaker (RCCB) designed strictly for ground fault protection. It must be paired with an appropriate upstream circuit breaker or fuse for overload and short-circuit protection.
