Overview
The Bussmann KTK-10 LIMITRON is a fast-acting, supplemental fuse rated for 10 amperes at 600VAC with a 100kA interrupt capacity. KTK fuses are fast-acting, supplemental fuses designed to provide reliable circuit protection in industrial, commercial, and HVAC applications. This lot of 6 units features ferrule end connections, nickel-plated bronze endcaps, and melamine tube construction, making them suitable for control circuits, lighting circuits, and meter circuit applications where compact protection is critical.
Key Features
- Fast-acting, supplemental protection design
- 100 kAIC interrupt rating at 600V
- Designed as midget fuses for supplemental protection to industrial, commercial, agricultural, HVAC equipment
- Often used to protect internal components such as control circuit wiring and motor control transformers
- Melamine tube with nickel-plated brass endcaps
- UL Listed (STD. 248-14, Guide #JDYX, File #E19180) and CSA Certified
Technical Specifications
The KTK-10 meets UL and CSA standards for supplemental fuse applications. Its compact midget format integrates into space-constrained control circuits while maintaining high interrupting capacity. The ferrule-style terminals ensure secure mounting in compatible fuse holders.
Typical Applications
- Control circuit protection in industrial control panels
- Lighting circuit branch protection
- Meter circuit safeguards
- Motor control transformer protection
- HVAC and refrigeration equipment circuits
- Specialty industrial and commercial automation systems
