The Senva CVT-FUSE-C6 is a blue-lead in-line fuse kit for Senva CVT Current/Voltage Transducer installations, providing a 1/2 Amp, 600VAC slow-blow fuse with a 200kA AC interrupting rating. It supplies the overcurrent protection required when a CVT voltage reference run exceeds 20 ft (runs under 10 ft require no fusing per UL 240.21 tap-rule guidance).
Senva CVT-FUSE-C6 CVT Fuse Kit
Senva's CVT architecture keeps all high-voltage connections within the CVT enclosure, and per UL 240.21 tap-rule guidance no overcurrent protection is required for voltage reference runs under 10 ft. When a reference run must exceed 20 ft, this in-line fuse kit provides the required protection without consuming panelboard breaker space.
Best For
- CVT voltage reference runs over 20 ft
- Remote meter base placement outside the panel
- Retrofit metering with long wiring paths
Key Features
1/2A 600VAC Slow Blow
Correctly sized protection for CVT voltage reference taps, with a 200kA AC interrupting rating.
Blue Lead for Phase ID
Matches the blue-lead CVT phase color convention for clean, phase-identified installs.
For Long Reference Runs
Required when a CVT voltage reference must exceed 20 ft; runs under 10 ft need no overcurrent protection per UL 240.21 guidance.
In-Line Simplicity
Installs directly in the CVT voltage reference wiring — no panelboard breaker space needed.

Frequently Asked Questions
When do I need the CVT-FUSE-C6?
When a CVT voltage reference run exceeds 20 ft. Senva ships EM Series meters with no more than 10 ft of voltage reference wire per CVT, and runs under 10 ft require no overcurrent protection per UL 240.21 tap-rule guidance.
What fuse does the kit use?
A 1/2 Amp, 600VAC slow-blow fuse with a 200kA AC interrupting rating — matched to the CVT voltage reference circuit.
What does the blue lead indicate?
Lead color follows the CVT phase color convention (black, red, blue), so the fuse kit can match the phase it protects.
