Information About THQB32070ST1
The THQB32070ST1 is part of GE’s Q-Line series, designed to provide durable molded case protection for multi-phase distribution equipment. Its THQB construction incorporates a bolt-on connection, molded housing, and an integrated 120 V shunt trip, supporting applications requiring remote safety shutdown. The breaker integrates smoothly into panelboards and distribution assemblies using Q-Line mounting patterns and load-side lug terminals. Commonly used in commercial electrical systems and facility power distribution, it employs thermal magnetic technology and LI trip functions to support both long-time overload management and instantaneous short-circuit interruption.
Key Features:
- 70 A rating: Supports medium-capacity loads in three-phase applications.
- 240 V operation: Designed for standard low-voltage distribution systems.
- Bolt-on connection: Ensures secure mechanical fastening and reliable panelboard integration.
- 120 V shunt trip included: Enables remote tripping for safety interlock or emergency shutdown systems.
- LI trip functions: Provides long-time overload and instantaneous short-circuit protection.
- Thermal magnetic protection: Delivers consistent performance for both overload and fault conditions.
- 3-pole configuration: Suitable for balanced three-phase load distribution.
- 10 kA interrupt rating: Supports fault clearing at 208 V levels.
The THQB32070ST1 delivers the reliability and precision required for molded case circuit protection in commercial and industrial power systems.
