Replacement RCCB for 120v residential panel,120V RCCB
US 120V RCCB 2‑Pole 30mA Residual Current Protector 6A 10A 16A 20A 25A 32A 40A 50A 63A 80A Replacement for Home Electrical Panel
This 120V 2‑pole RCCB residual current circuit breaker is a direct‑fit replacement device for US residential electrical panels, covering rated current 6A‑80A and fixed 30mA residual operating current. It delivers ground‑fault leakage protection for household circuits, complies with North‑American low‑voltage residential application requirements. It serves as safety upgrade or drop‑in replacement for existing RCCB units for 120V single‑phase living space wiring.
Rated electrical specifications
This RCCB is designed for 120V US residential single‑phase system.
Rated voltage: AC 120V, 2‑pole configuration.
Supported rated current range: 6A,10A,16A,20A,25A,32A,40A,50A,63A,80A
Leakage protection performance
The residual operating current is fixed at 30mA.
It trips rapidly when earth leakage reaches 30mA to prevent electric shock hazards.
Standard trip response time: ≤40ms under rated residual current.
Application & installation compatibility
Unit is made as replacement part for US standard residential distribution panels.
Suitable for 120V household lighting, socket and small‑power branch circuits.
It only applies to single‑phase 120V system, not for 240V main‑line direct use.
Core safety features
Provides human‑body electric shock protection and circuit leakage fire prevention.
No over‑current short‑circuit protection built‑in; match with MCB for full protection.
Working ambient temperature range:‑5℃ ~ +40℃ for indoor residential installation.
FAQ
Q1: Can this RCCB work on 240V US circuits?
A: No. This model is strictly rated for AC120V single‑phase residential panel, 240V input will damage the device.
Q2: Does this breaker include overload & short‑circuit protection?
A: Yes, It provide residual current RCCB. Also provides leakage protection and overload and short‑circuit safeguard.
Q3: What does 30mA mean for end‑user safety?
A: 30mA is the global household standard residual action value. It cuts power fast to reduce fatal electric‑shock risk for human contact.
Q4: Which amp rating should I pick for home replacement?
A: Match your original old RCCB rated current. Common household options:20A for general outlets,32‑63A for main branch circuit.
