Product Overview
When human interaction with active 3-phase electrical equipment is frequent, basic overcurrent protection is dangerously inadequate. The CHNAILE Ultimate Safety 4-Pole Residual Current Breaker with Overcurrent Protection (RCBO) provides an impenetrable shield against fatal electric shocks and equipment-destroying power surges. Finely calibrated for 16-Ampere (approx. 11kW) continuous loads across an AC 400V network, this integrated module strictly monitors earth leakage down to the life-saving 30mA threshold. Compliant with the international IEC61009-1 standard, it guarantees simultaneous 4-pole disconnection, rendering it essential for modern EV infrastructure and precision commercial installations.

1. High-Precision Life & Asset Protection
30mA Life-Saving Threshold: Unlike heavy-industrial breakers, the internal smart-core is exquisitely sensitive. It instantly detects minor leakage currents (as low as 30mA) escaping to the earth through human contact or degraded insulation, severing power within 0.1 seconds to prevent fatal electrocution.
Synchronized 4-Pole Severance: Upon detecting a fault, the mechanically linked green toggles drop simultaneously, completely isolating L1, L2, L3, and the Neutral wire. This absolute severance guarantees a zero-voltage state for safe technical servicing.
Integrated Arc-Quenching (6kA): Eliminates the need for a separate MCB. It actively defends against massive 6000A short-circuit flashes, cooling and dissipating explosive arcs internally to protect the surrounding panel components.
2. Engineering & Material Excellence
Hygienic, Fire-Retardant Casing: Manufactured from V0-grade thermosetting polymers. The enclosure resists high ambient temperatures and prevents fire propagation, making it safe for indoor laboratories and commercial utility rooms.
Routine Safety Diagnostic Button: Features a dedicated yellow 'T' (Test) button designed for monthly functional checks. This allows facility managers to physically verify the health of the residual current monitoring circuit without calling an electrician.
Vibration-Proof Rail Grip: Equipped with a reinforced bottom locking clip that anchors the breaker firmly to 35mm DIN rails, ensuring stability even inside vibrating commercial washing systems or EV charging pillars.
3. Target Application Scenarios
Due to its precise 16A capacity and strict 30mA human-safety rating, this 4P RCBO is highly specified by global EPC contractors for:
11kW AC EV Charging Stations: Serving as the mandatory incoming protection for 3-phase Level 2 electric vehicle Wallboxes, protecting users during plug-in operations in wet outdoor conditions.
University & Medical Laboratories: Providing dedicated, isolated branch protection for expensive 3-phase testing equipment, centrifuges, and research apparatus.
Commercial Kitchens & Bakeries: Safeguarding stainless steel environments where staff interact with 3-phase ovens, dough mixers, and dishwashers near water sources.
School & Educational Workshops: Essential life-saving disconnects for 3-phase training lathes, 3D printers, and woodwork machinery.
