Why Choose the ABB S2C-NT Hand Operated Neutral?
The ABB S2C-NT is a hand operated neutral designed for use with compatible ABB modular circuit protection devices where the neutral conductor needs to be manually opened for measurement duties. Identified by ABB order code 2CDS200918R0001, it forms part of ABB's MCB accessories portfolio and System pro M compact range.
The S2C-NT is mounted on the left-hand side of the associated MCB or switch disconnector and snaps onto the DIN rail. Its manually operated mechanism allows the neutral conductor to be placed in the open position when required, making it particularly useful for testing and measurement applications in professional electrical distribution systems.
A key feature of the S2C-NT is its switching sequence: when the associated MCB is switched on, the neutral contact makes before the MCB closes, while the neutral opens after the MCB during switching off. The accessory is rated up to 40 A, uses a 10 mm² cage terminal and is compatible with ABB S200-series miniature circuit breakers and selected related modular devices.
Key Advantages
- Provides manual isolation of the neutral conductor for measurement duties.
- Make-before-close switching sequence ensures the neutral is connected before the associated MCB closes.
- Designed for convenient left-side mounting on compatible ABB modular devices.
- DIN-rail mounting integrates neatly into modular distribution assemblies.
- Rated for applications up to 40 A.
- Compatible with multiple ABB S200-series miniature circuit breaker variants.
Key Features
- Hand operated neutral accessory.
- Maximum rated current: 40 A.
- 10 mm² cage terminal.
- 1.2 Nm terminal tightening torque.
- Left-side mounting on the associated modular protection device.
- Snaps directly onto a standard DIN rail.
- Designed for measurement duties requiring an open neutral conductor.
- Neutral makes before the associated MCB closes during switch-on.
- Compatible with ABB S200, S200 MT, S200 P, S200 MUC and S300 P devices.
- ABB order code 2CDS200918R0001.
Manual Neutral Isolation for Measurement Applications
A hand operated neutral provides a controlled method of opening the neutral conductor in electrical installations where measurement or testing procedures require neutral isolation. The ABB S2C-NT integrates alongside compatible modular protection devices and provides a dedicated manually operated neutral contact without requiring a separate standalone switching arrangement.
The S2C-NT incorporates a deliberate switching sequence so that the neutral closes before the associated circuit breaker during switch-on and opens after the circuit breaker during switch-off. This design, combined with its compact 8.8 mm width and DIN-rail mounting arrangement, makes it a practical accessory for professional ABB modular distribution systems.
Typical Applications
- Electrical measurement and testing duties.
- Distribution boards requiring manual neutral isolation.
- ABB S200-series miniature circuit breaker assemblies.
- DIN-rail modular protection systems.
- Commercial and industrial electrical installations.
- Control and distribution panels using compatible ABB modular devices.
