2-pin or 4-pin
Detects AC and pulsing DC fault currents
Surge-proof up to 250 A and therefore resistant to short leakage currents to earth
DIN rail assembly

1 changeover contact
A maximum of three S2C-S / H6R can be installed in sequence

  DIN VDE 0664 part 11, DIN VDE 0664 part 1 // 10.85, EN 61008-2-1

Increase workplace safety with this 2-pole RCCB from ABB. It detects AC and DC earth fault currents and immediately breaks the circuit to protect people and equipment. A trip sensitivity of 300mA reduces nuisance tripping when used with heavy-duty applications. Thanks to an electrical lifespan of 10,000 cycles, the unit delivers consistent performance. Compact dimensions of 35 (W) x 85 (H) x 69mm (D) mean it fits easily into densely-packed systems. Simply snap it onto a DIN rail for effortless installation.

• Lightweight component of 200g puts minimal strain on DIN rails and enclosures
• 25A current rating makes it widely compatible
• Broad operating temperature between -25°C and +55°C for use in demanding conditions

• Medical equipment
• Residential buildings
• Food and beverage processing plants

A residual current circuit breaker, or RCCB for short, works by comparing the currents entering and leaving a device. The RCCB senses when there's a current difference between the incoming (live) current and the outgoing (neutral) current, also known as residual current, and trips the circuit.
