About This Product
This dual-element, current-limiting, time-delay Class RK5 fuse pack (2-pack) is designed to provide dependable circuit protection for equipment such as power panelboards, motor control centers, and safety switches. Its dual-element design separates overload and short-circuit protection, allowing temporary inrush currents without opening the fuse. The time-delay feature helps accommodate brief overloads that commonly occur during motor or transformer startup, which can help reduce unnecessary fuse replacement. These fuse cartridges are UL and CSA listed for safety.
Highlights
- Suitable for use in power panelboards, motor control centers, combination starters, and machinery disconnects
- Rated for a maximum of 25 Amps and 250 Volts
- UL and CSA listed
- Closer sizing allows the use of smaller fuses and lower-cost switches
- Helps protect motors from burnout caused by overloads and single-phasing on three-phase systems
- Helps simplify and improve selective coordination for blackout prevention
- 2:1 selective coordination amp ratio within the RK5 fuse family helps prevent overcurrent events from opening upstream fuses
- Dual-element design can be used in circuits subject to temporary motor overloads and surge currents, providing both short-circuit and overload protection
- The overload element helps protect against low-level overcurrent and can hold an overload up to five times the fuse amp rating for a minimum of 10 seconds
