Why Choose the ABB 1SDA073891R1 Lever Interlock?

The ABB 1SDA073891R1 is a lever interlock accessory for ABB Emax 2 E6.2 three-pole air circuit breakers. Designed as part of the ABB Emax 2 mechanical accessory range, it provides a dedicated mechanical interlocking component for compatible E6.2 circuit breaker installations.

Mechanical interlocking is used where the operating states of multiple circuit breakers must be coordinated. The lever mechanism forms part of an interlocking arrangement that mechanically transfers breaker position or operating state, helping prevent incompatible switching combinations when correctly installed within the specified system.

This version is specifically identified for the ABB Emax 2 E6.2 3P frame configuration. As a passive mechanical accessory, the lever interlock itself does not depend on an auxiliary control voltage for its interlocking action, making it suitable for switchboards requiring mechanically enforced operating sequences.

Key Advantages

  • Purpose-designed mechanical lever interlock for ABB Emax 2.
  • Specifically intended for the E6.2 three-pole circuit breaker configuration.
  • Supports mechanically controlled circuit breaker operating sequences.
  • Helps prevent incompatible breaker combinations when incorporated into the correct interlocking system.
  • Mechanical interlocking action does not rely on an auxiliary control supply.
  • Genuine ABB accessory designed for compatible Emax 2 switchgear assemblies.

Key Features

  • ABB Emax 2 lever interlock accessory.
  • Designed for the E6.2 circuit breaker frame.
  • Three-pole (3P) configuration.
  • Mechanical interlocking function.
  • Suitable for use as part of a compatible multi-breaker interlocking arrangement.
  • Supports controlled breaker operating sequences in low-voltage switchgear.
  • Passive mechanical operation.
  • ABB order code 1SDA073891R1.

Mechanical Lever Interlocking for Emax 2 E6.2

Circuit breaker interlocking is commonly used in power distribution systems where two or more breakers must follow a defined operating relationship. A mechanical interlock provides a physical constraint between compatible breakers, helping ensure that switching operations follow the intended sequence independently of electrical control logic.

The ABB 1SDA073891R1 provides the lever-interlock component specifically associated with the Emax 2 E6.2 three-pole configuration. The complete interlocking arrangement must be selected according to the number, position and configuration of the circuit breakers involved, so compatibility with the other interlock components should be confirmed during switchboard design or replacement.

Typical Applications

  • ABB Emax 2 E6.2 three-pole air circuit breaker installations.
  • Mechanical interlocking between compatible circuit breakers.
  • Main and standby power distribution arrangements.
  • Generator and mains switching schemes.
  • Industrial low-voltage switchboards.
  • Power distribution systems requiring mechanically controlled breaker sequences.

Frequently Asked Questions

What is the ABB 1SDA073891R1?

The ABB 1SDA073891R1 is a mechanical lever interlock accessory designed for ABB Emax 2 E6.2 three-pole air circuit breakers.

Which ABB circuit breaker is the 1SDA073891R1 designed for?

The 1SDA073891R1 is specifically identified for the ABB Emax 2 E6.2 three-pole (3P) circuit breaker configuration.

What does a lever interlock do on an Emax 2 circuit breaker?

A lever interlock forms part of a mechanical interlocking arrangement between compatible circuit breakers, helping enforce the required operating relationship and prevent incompatible breaker combinations.

Does the ABB 1SDA073891R1 require an auxiliary electrical supply?

No. The 1SDA073891R1 is a mechanical interlock accessory, so its basic interlocking action does not require an auxiliary electrical supply.

Can the ABB 1SDA073891R1 be used as a complete interlocking system on its own?

The 1SDA073891R1 is a lever interlock component for the compatible E6.2 3P configuration. A complete interlocking scheme can require additional mechanical interlock components selected according to the breaker arrangement, so the full system configuration should be checked before installation.
