Why Choose the ABB YO E1.2..E6.2 48 VAC/DC Shunt Opening Release?
The ABB YO E1.2..E6.2 48 VAC/DC, order code 1SDA073670R1, is an electrical opening accessory for ABB SACE Emax 2 circuit breakers. Designed as a shunt opening release (YO), it enables compatible circuit breakers to be opened electrically when a control voltage is applied.
Rated for a 48 V AC/DC control supply, the release can operate from either alternating-current or direct-current control circuits. ABB specifies the accessory for E1.2, E2.2, E4.2 and E6.2 SACE Emax 2 frame sizes, providing a common remote-opening solution across the principal Emax 2 range.
The YO release is intended for applications requiring remote or electrically initiated circuit-breaker opening, including switchboards, industrial distribution systems and automated control schemes. ABB identifies YO accessories as first or second shunt opening coils, with a second YO providing an alternative accessory arrangement where compatible with the breaker configuration.
Key Advantages
- 48 V AC/DC control voltage supports both AC and DC control circuits.
- Provides electrical remote opening of compatible SACE Emax 2 circuit breakers.
- Compatible with E1.2, E2.2, E4.2 and E6.2 frame sizes.
- Designed specifically for the ABB SACE Emax 2 circuit-breaker platform.
- Can be used as a first or second shunt opening coil in compatible configurations.
- Suitable for integration into automated control and protection schemes.
- Supports remote trip commands from control panels, relays and supervisory systems.
- ABB-engineered accessory provides direct compatibility with the intended breaker platform.
Key Features
- ABB YO shunt opening release.
- 48 V AC/DC rated control supply.
- AC/DC actuating voltage type.
- Built as a switch-off coil.
- Compatible with SACE Emax 2 E1.2–E6.2.
- Provides electrically initiated circuit-breaker opening.
- Suitable as a first or second YO release in compatible breaker configurations.
- Designed as an Emax 2 electrical accessory.
- Suitable for remote control and protection applications.
- Rated for 48 V AC at 50/60 Hz and 48 V DC control supplies.
Reliable Remote Circuit-Breaker Opening
The YO shunt opening release converts an external electrical command into a circuit-breaker opening action. When the appropriate 48 V AC/DC control signal is applied, the release actuates the opening mechanism of the compatible SACE Emax 2 circuit breaker, allowing the breaker to be tripped without direct manual operation.
This functionality is valuable in remotely controlled switchboards and automated power systems where circuit-breaker opening may be initiated by a control station, protection system or supervisory scheme. Compatibility across E1.2 through E6.2 frame sizes also allows the same voltage variant to be specified across a broad range of Emax 2 installations.
Typical Applications
- Remote opening of ABB SACE Emax 2 air circuit breakers.
- Industrial low-voltage distribution switchboards.
- Automated circuit-breaker control systems.
- Protection and emergency trip control circuits.
- Building and infrastructure power distribution systems.
- Switchgear requiring a 48 V AC/DC electrically operated opening release.
