Downtime Is Expensive. Smart Protection Isn't. With our new MT40 ThermoFuse varistors, we introduce a compact surge protection solution engineered for extreme electrical environments - delivering up to 50 kA peak surge capability in a minimized footprint.
Designed for industrial power supplies, PV systems, telecom infrastructure and SPDs, the MT40 series combines:Up to 50 kA (8/20 µs) surge capability
Short-circuit current rating up to 200 kA (UL 1449)
Integrated thermal disconnect system
Galvanically insulated micro-switch for remote monitoring
Compact, overmolded design for optimized integration
UL 1449 Type 1CA recognized for AC and DC applications, RoHS/REACH/PFAS compliant, and encapsulated in flame-retardant epoxy - MT40 supports robust, safety-driven and sustainable system design.
If your application demands high surge endurance without sacrificing space or safety, this is worth a closer look:
