Our front mounted auxiliary contacts do not add depth to the motor protection circuit breaker and installs within its foot print - no extra panel area is required. IP20 guarded terminals protect against accidental contact with live parts. These contacts snap-on and install without the use of tools.

Our side mounted auxiliary contacts feature IP20 guarded terminals to protect against accidental contact with live parts. These contacts snap-on to the left side of the motor protection circuit breaker and install without the use of tools.

The trip indicating auxiliary contact module includes overload contacts and short circuit contacts. When an overload trip occurs the overload contacts change state. When a short circuit occurs, the overload contacts and short circuit contacts change state. In addition to the electrical contacts, the trip indicating auxiliary contact module includes a mechanical trip indication - the blue button protrudes from the module after a short circuit trip. Can be installed without the use of tools. Note: The trip indicating auxiliary contact and the line side terminal barrier are required to achieve Type E construction with a Series 330-T25S device.

The line side terminal barrier provides increased electrical clearances to comply with the UL 60947-4-1 Self-Protected Combination Motor Controller (Type E) requirements. The terminal barrier can be field installed on MPCBs. Note: The line side terminal barrier and the trip indicating auxiliary contact are required to achieve Type E construction with a Series 330-T25S device.

The shunt release module enables the motor protection circuit breaker to be turned "OFF" from a remote location. Snaps-on and installs on the right side of the MPCB without the use of tools. IP20 guarded terminals to protect against accidental contact with live parts. Wide range of 50/60Hz operating voltages. Can be used in conjunction with front mounted and side mounted auxiliary contacts.

The undervoltage release module automatically trips the motor protection circuit breaker when the supply voltage is less than 70 - 35% of the rated voltage of the undervoltage release module. Undervoltage release modules are ideal to ensure motors do not automatically restart after a power outage when the MPCB is being used by itself as a manual motor controller. Snaps-on and installs on the right side of the MPCB without the use of tools. IP20 guarded terminals to protect against accidental contact with live parts. Wide range of 50/60Hz operating voltages. Can be used in conjunction with front mounted and side mounted auxiliary contacts.

The feeder terminal accepts the main branch circuit conductors and distributes power to the 330-CL commoning links. The feeder terminal overlaps the commoning link when installed. IP20 guarded terminals to protect against accidental contact with live parts. Continuous current rating: 63A.

Commoning links provide a convenient means of distributing 3-phase power to a group of motor protection circuits. 45mm spacing commoning links are for use with motor protection circuit breakers without auxilary contact modules or with a front mounted auxiliary contact module. 54mm spacing commoning links are for use with motor protection circuit breakers with a side mounted auxilary contact module. IP20 construction to guard against accidental contact with live parts. Used in conjunction with Feeder Module.

The adjustment scale cover prevents inadvertent or unauthorized adjustment of the full load current dial setting of the motor protection circuit breaker.

The highly visible yellow terminal shroud with the hazard symbol is for covering unused terminals of the 330-CL commoning links. Use of the shroud insulates the unused terminals and enables the easy installation of additional motor protection circuit breakers in the future.

The circuit breaker - contactor link module provides a mechanical and electrical linkage between a motor protection circuit breaker and a Series 300 Contactor. The link module makes starter assembly easy and enables the starter assembly to be installed on a single or two 35mm DIN rails.

The mounting foot kit enables motor protection circuit breakers to be panel mounted instead of installed on a 35mm DIN rail.

Our external operating handles provide reliable actuation of Series 330 MPCBs and Series 630 DOL Starters from the outside of the enclosure and can be padlocked OFF with up to three padlocks. Door interlock can be opened in the OFF position. Operating shaft can be cut to length to fit in enclosures up to 421mm (16-37/64") deep.

The enclosure accessory is a custom fit design specifically for use with our Series 330 Motor Protection Circuit Breakers. CE certified with an IP55 environmental rating.

Available in two frame sizes: Frame size 1 - 55mm internal mounting width allows the assembly of a side mounted auxiliary contact, and Frame size 2 - 65mm internal mounting width allows the assembly of a shunt release module or undervoltage module.

The enclosure has integrated ground and neutral connections, and 4 standard PG16 knock outs (2 on the top and 2 on the bottom).

The operating handle can be padlocked in the "OFF" position with up to 3 padlocks.
