Why Choose the ABB S3C-H-S/H6R Auxiliary & Signal Contact?
The ABB S3C-H-S/H6R is a compact combined auxiliary and signal contact designed for status monitoring and remote signalling with compatible ABB modular protection devices. Supplied under ABB order code 2TAZ940070R0001, it combines two changeover contacts in a space-saving half-module accessory.
The S3C-H-S/H6R provides one dedicated auxiliary changeover contact together with a second changeover contact that can be selected for either auxiliary or signal operation. In auxiliary mode it indicates the switching position of the associated device, while signal mode can indicate a protective trip caused by conditions such as overcurrent, short circuit, earth leakage or arc fault, depending on the connected protection device.
Designed for right-side mounting, the accessory is compatible with a broad range of ABB System pro M compact devices, including S200, S200M, S200P, S300P, F200, DS200, DS201, S-ARC1, DS-ARC1 and SD200 families. Its width of only 8.8 mm helps provide comprehensive signalling functionality while conserving valuable DIN-rail space.
Key Advantages
- Combines auxiliary and signal contact functions in one compact accessory.
- Two changeover contacts within only half a modular spacing.
- Selectable auxiliary or fault-signalling function on one changeover contact.
- Provides remote indication of device position and protective tripping.
- Broad compatibility across ABB System pro M compact protection devices.
- Right-side mounting for straightforward integration with compatible devices.
Key Features
- ABB S3C-H-S/H6R auxiliary and signal contact.
- 2 changeover (CO/SPDT) contacts.
- One auxiliary contact plus one selectable signal/auxiliary contact.
- 10 A conventional free-air thermal current.
- AC-14 utilisation ratings up to 1 A at 400 V AC and 2 A at 230 V AC.
- DC-13 utilisation ratings of 2 A at 60 V DC and 4 A at 24 V DC.
- 10,000-operation mechanical endurance.
- Conductor capacity of 0.75–2.5 mm².
- Compact 8.8 mm width equivalent to half a modular spacing.
Compact Status and Trip Signalling for ABB Protection Devices
Auxiliary contacts allow the switching position of a circuit protection device to be communicated to external monitoring, indication or control equipment. The S3C-H-S/H6R extends this functionality by allowing one of its changeover contacts to operate as a signal contact, enabling differentiation between normal switching status and a protective trip.
Its two changeover contacts are integrated into only half a module of DIN-rail width, making the S3C-H-S/H6R particularly useful where panel space is limited. Compatibility with numerous ABB MCB, RCCB, RCBO, AFDD and switch-disconnector families also enables a common signalling accessory to be used across a wide range of modular protection applications.
Typical Applications
- Remote circuit breaker status indication.
- Protective trip and fault signalling.
- Industrial control and automation panels.
- Commercial electrical distribution boards.
- Building management and monitoring systems.
- ABB MCB, RCCB and RCBO installations.
- ABB AFDD and switch-disconnector installations.
