Description
Delivering reliable performance, the GE THLC136030WL is a 3-pole, 30A current-limiting MCCB. It utilizes a thermal-magnetic trip unit for long-time and instantaneous protection. The unit-mount design allows for installation in GE switchboards, motor control centers, and standalone enclosures. With a 200 kAIC interrupting capacity at 480VAC, it effectively limits peak fault currents. This HACR-rated breaker ensures superior system protection.Specifications

Product FAQs
7 answersWhat types of equipment are compatible with the THLC136030WL breaker?
This unit-mount breaker is designed for installation in GE switchboards, motor control centers (MCCs), and individual enclosures. It is not designed for standard load centers or panelboards that require plug-in or bus-connected bolt-on mounting.
How does the current-limiting feature of the THLC136030WL benefit my electrical system?
As a current-limiting breaker, it clears short-circuit faults extremely fast, significantly reducing the peak let-through current and thermal energy. This provides enhanced protection for downstream components and wiring against severe electrical faults.
How does the interrupting capacity (AIC) of the THLC136030WL change across different voltages?
The breaker provides a maximum interrupting rating of 200kAIC at both 240VAC and 480VAC. However, when applied in 600VAC systems, the interrupting capacity is reduced to 50kAIC. Always verify the available fault current at your specific operating voltage.
Are terminal lugs included with the THLC136030WL, and what wire materials are supported?
Yes, the WL suffix in the catalog number indicates that the breaker comes with factory-installed line and load lugs. These feed-thru terminals are dual-rated, accepting 14 to 8 AWG copper (Cu) conductors or 12 to 8 AWG aluminum (Al) conductors.
Can I adjust the trip settings on the THLC136030WL?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time (overload) and instantaneous (short-circuit) trip functions are factory-calibrated for 30 amps and cannot be adjusted in the field.
How does the thermal-magnetic trip unit in the THLC136030WL operate?
The thermal element relies on a bimetallic strip that heats up and bends to trip the breaker during sustained overloads. The magnetic element uses an electromagnetic coil to provide an instantaneous trip response when a high-level short circuit is detected.
Can the THLC136030WL be used to replace older THLC1 frame breakers?
Yes, it is a direct replacement for existing 30A, 3-pole THLC1 frame breakers used in GE switchboards and motor control centers. The WL suffix ensures it includes standard line and load lugs for a direct swap.
