2CSR275151R0065 ABB DSE201 M B6 A10 6 A 10 mA Type A 10 kA RCBO

Why Choose the ABB DSE201 M B6 A10 RCBO?

The ABB DSE201 M B6 A10 is a compact 1P+N voltage-dependent residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and earth leakage faults. As part of the ABB DSE201M / DSE203NM 10 kA RCBO range, it combines overcurrent and residual-current protection within a single modular device.

This RCBO has a 6 A rated current, B tripping characteristic and Type A residual-current detection. Its 10 mA rated residual operating current provides sensitive earth-leakage protection, while Type A operation detects both sinusoidal alternating residual currents and pulsating DC residual currents.

With a rated short-circuit capacity of 10 kA, an unswitched neutral and voltage-dependent operation, the DSE201 M B6 A10 provides coordinated circuit protection in a compact format. Its B-curve characteristic is suited to appropriately designed circuits with relatively low inrush currents, while the Type A characteristic extends residual-current detection to loads incorporating electronic components.

Type A 10 mA Residual-Current Protection

The ABB DSE201 M B6 A10 combines overload and short-circuit protection with Type A residual-current detection in one modular protective device. Type A RCBOs respond to sinusoidal alternating residual currents as well as pulsating DC residual currents, making them suitable for appropriately specified circuits containing electronic equipment capable of producing pulsating DC earth fault components.

Its sensitive 10 mA residual operating current is combined with a 6 A B-curve overcurrent characteristic and 10 kA short-circuit capacity. This combination provides coordinated protection for suitable low-current commercial and industrial circuits while retaining the space-saving benefits of a combined RCBO.

Typical Applications

• Commercial single-phase electrical circuits.
• Industrial auxiliary and control circuits.
• Low-current circuits within the 6 A device rating.
• Circuits supplying loads with relatively low inrush currents.
• Electrical distribution boards and control panels.
• Circuits containing electronic equipment that may produce pulsating DC residual currents.
• Applications requiring sensitive 10 mA Type A residual-current protection.
