- Voltage Rating: 250 V AC
- Interrupting Rating: 50 kA (50,000 amperes)
- Fuse Class: Class K5
- Mounting Type: Clip
- Connection Type: Ferrule
- Insulation Material: Paper
- Dimensions: Length 2 in, Diameter 0.56 in, Width 0.56 in, Height 0.56 in
- Product Weight: 0.0290 lbs
- Manufacturer: Mersen
- Manufacturer Part Number: OT25
- Application: Feeders, branch circuits, resistive heating, residential and small commercial installations
Specifications
- One-time use fuse providing cost-effective protection for lighting and heating circuits
- Fast-acting fuse type for rapid interruption of overcurrent conditions
- Capable of safely interrupting short-circuit currents up to 50,000 amperes
- Meets Canadian electrical code requirements for Type P low melting-point, non-time-delay fuses (OTN 15-60)
- Not a rejection fuse—replacement fuses must have equal or higher interrupting ratings
- Compact size suitable for residential and small commercial switchgear and electrical panels
