The Hager RCBO 32A B Curve Type A Single Pole 2 Module 6kA ADA932U is a compact protection device that combines miniature circuit breaker (MCB) overcurrent protection and residual current (RCD) earth fault protection in a single unit. Rated at 32A with a 30mA residual operating current, it is designed for final circuits in domestic and light commercial installations where both overload/short-circuit protection and additional protection against electric shock are required.
B Curve, Type A Safety with 6kA Breaking Capacity
With a B-curve tripping characteristic, the ADA932U is suited to general-purpose circuits with predominantly resistive or lightly inductive loads, such as lighting and socket circuits, providing fast disconnection without nuisance tripping. Its Type A residual current function detects AC and pulsating DC earth leakage, supporting compliance with modern wiring regulations. A 6kA short-circuit breaking capacity at 230–240V AC in accordance with IEC 60898-1 ensures dependable fault clearance and coordinated protection within Hager consumer units and distribution boards.
Compact 2-Module, 1P+N Design for Easy Installation
Configured as a 1P+N (single pole with switched neutral) device in a 2-module housing, this RCBO mounts directly onto DIN rail for quick, space-efficient installation. Screw terminals with a biconnect bottom connection accept 1–16mm² flexible and 1–25mm² rigid conductors, tightened to 2.10Nm for secure terminations. With an IP20 rating, operating temperature range of -25°C to +40°C, total power loss of 8.30W and compact dimensions of 83mm (H) x 35mm (W) x 68mm (D), the ADA932U is a robust choice for new boards and retrofit upgrades alike.
