Features and Benefits

Ratchet-Type Mounting

• 15–1200 A frame circuit breakers require only a screwdriver and are firmly attached to the bus stack and mechanically attached to the interior assembly.

• The connectors are an integral part of the I-Line circuit breaker—eliminating the assembly of connectors to the bus bar.

• Pre-assembled hardware means reduced installation time.

• The unique line side connection requires no routine maintenance.

I-Line Bus Structure and Circuit Breaker Mounting

Push-to-trip is a standard feature on all I-Line circuit breakers. It is useful for checking circuit breaker operation and for testing auxiliary devices. The circuit breaker is mechanically tripped by pressing the push-to-trip button in the circuit breaker case.

Blow-On Connections

All circuit breaker connections are “blow-on” type. Under high-level short circuit conditions, the magnetic forces developed tend to draw the connector jaws together, gripping the I-Line bus bar more firmly.

• SCCR is equal to the lowest interrupting capacity of a branch or main circuit breaker installed in the panelboard.

• I-Line panelboards, with branch circuit breakers installed, are short-circuit tested as complete units.

• All tests are conducted in accordance with UL 67 and CSA C22.2 (Standards for Panelboards).

With I-Limiter main circuit breaker, I-Line main circuit breaker panelboards are UL/CSA Listed for use on systems with up to a 200,000 maximum RMS symmetrical amperes available fault current (100 kA @ 600 Vac).
