Overview

The ABB THQC1115LL is a 1-pole, 15 Amp Q Line miniature circuit breaker designed for residential, commercial, and light industrial applications. This QC (lug-lug) version features a compact one-inch width per pole, enabling high-density installations in 35mm DIN rail systems. Engineered as a thermal-magnetic device, it provides reliable overcurrent protection with fixed long-time and instantaneous trip functions. The breaker includes Quick-make / Quick-break mechanisms for consistent performance and common trip bars for coordinated multi-pole protection. A visible trip indicator ensures immediate fault identification. Rated for 120/240 Vac systems, the THQC1115LL offers a 10 KAIC interrupting rating at both 120 Vac and 120/240 Vac. It supports reverse feed applications and is suitable for HACR (Heating, Air Conditioning, and Refrigeration) and SWD (Switching Duty) for 120 Vac fluorescent lighting loads. The non-interchangeable trip style ensures fixed protection settings, eliminating tampering risks. Optional accessories such as auxiliary contacts and shunt trips are available for enhanced control and monitoring. Compatible with standard 35mm DIN rail mounting, the THQC1115LL integrates seamlessly into modern electrical panels and control systems. SKU: THQC1115LL.
