EATON FRBMM-C16/3/003-A RCBO, 16 A, 30 mA, typ A, charakteristika C, 3-pólový + N, 6 kA, 4 TE 170740

Combines residual current protection (30 mA, Type A) and overcurrent protection (C-curve, 16 A) in a single 4-module device, with a 6 kA breaking capacity for reliable circuit protection in residential and commercial installations.

Overview

The EATON FRBMM-C16/3/003-A is a residual current circuit breaker with overcurrent protection (RCBO) that integrates the functions of an RCD and an MCB. It is designed for three-phase plus neutral circuits, providing protection against earth fault currents, overload, and short circuits. The device is suitable for DIN rail mounting and occupies 4 module widths (72 mm).

What stands out

• Rated residual current of 30 mA with Type A sensitivity, detecting AC and pulsating DC fault currents.
• C tripping characteristic (5–10 × In) for circuits with moderate inrush currents, such as lighting and socket outlets.
• 6 kA rated breaking capacity (Icn) and energy limitation class 3 for safe interruption of short-circuit currents.
• Compact 4-module design saves space in distribution boards.
• Surge current withstand capability of 3 kA (8/20 µs) reduces nuisance tripping.
