3 POLE RCBO (BUSBAR BOARDS COMPATIBLE)

3-Pole RCBOs Busbar Board Compatible Protection

AGM Electrical Supplies offers a reliable selection of 3-pole RCBOs designed specifically for busbar-compatible distribution boards. These devices combine circuit-breaker protection with residual-current detection in one compact unit, making them ideal for three-phase electrical systems in commercial, industrial, and demanding residential environments.

Key Features of the Available 3-Pole RCBOs

Compact 54 mm Profile

The 3-pole RCBOs in this category are built with a narrow 54 mm width, matching standard 3-pole MCB sizing. This allows seamless installation on busbar boards while conserving valuable switchboard space.

High Breaking Capacity

Each unit features a strong short-circuit rating, with models available in 10 kA performance. This ensures dependable fault-handling capability, protecting equipment and maintaining safety.

30 mA Type A RCD Protection

All RCBOs in this category provide 30 mA residual-current protection with Type A sensitivity. That means they detect both AC and pulsating DC leakage currents, ensuring enhanced protection against electrical shock risks.

C-Curve Tripping Profile

These RCBOs use a C-curve profile, making them suitable for circuits with moderate inrush currents. They handle equipment like motors, commercial appliances, and inductive loads without unnecessary tripping.

Neutral Switching & Status Indicator

Models include a neutral pigtail for secure neutral connection and reliable switching. Each RCBO also features a clear trip indication window, helping users easily identify whether the device is in the ON, OFF, or TRIPPED position.

Why Choose Busbar-Compatible RCBOs?

These units are ideal for three-phase panels using busbars, offering maximum safety, efficient wiring, and space-saving design. With combined overload, short-circuit, and earth-leakage protection in one device, they deliver complete peace of mind for critical circuits.
