The General Electric TECL36030 is a 3 Pole magnetic molded case circuit breaker with a current rating of 30 Amps and a voltage rating of 600VAC. It has an interrupting rating of 100kAIC at 480V. The TECL36030 has a feed-thru connection type and includes instantaneous trip functions.
What is the adjustable magnetic trip range for the TECL36030?
The instantaneous magnetic trip on this 30A motor circuit protector is adjustable from 90A to 390A. This allows you to tune the breaker to the specific locked-rotor inrush current of the motor it protects, preventing nuisance tripping during startup.
Can I use the TECL36030 as a standalone branch circuit breaker?
No. Under NEC and UL 489 guidelines, a magnetic-only motor circuit protector like the TECL36030 must be installed as part of a listed combination motor controller that includes a separate overload relay. It cannot be used for general branch circuit overcurrent protection.
What is the difference between the TEC36030 and the TECL36030?
Both are 30A, 3-pole Mag-Break motor circuit protectors in the GE E-Frame family. The difference is their interrupting capacity. The standard TEC36030 is rated for 10kAIC at 480V, while the TECL36030 is a current-limiting version rated for 100kAIC at 480V.
What equipment is compatible with the TECL36030?
This unit-mount motor circuit protector is designed for installation in GE Motor Control Centers (MCCs), combination motor starters, and GE A-Series or Spectra Series panelboards that accept E-Frame breakers.
Does the TECL36030 support reverse feeding?
Yes, the TECL36030 is UL listed for reverse feed applications. It features a feed-thru connection type with line and load side lug terminals for secure mounting.
How does the TECL36030 provide motor protection without a thermal element?
The TECL36030 is a Mag-Break device that responds only to short circuits and ground faults via its adjustable magnetic trip. Thermal overload protection must be handled separately by the overload relay in the motor starter. This division of labor allows the combination starter to ride through motor inrush currents while still clearing bolted faults in milliseconds.
