1. Fail-Safe without flames,explosion and arc when mains voltage 80~270V AC directly applied.
2. High Dielectric Withstanding Voltage up to 1KV.
3. Anti-Burst construction in a ceramic tube, resistant to humidity and insulation.
4. UL1412 approved.

Explosion-proof, high-stability, flame-retardant wire-wound resistors are resistive components designed for circuits requiring high safety and reliability, possessing excellent explosion-proof and flame-retardant properties.

Even when directly connected to an 80–270V AC power supply, they can still achieve safe failure without flame, explosion, or arcing.

The product adopts a ceramic tube encapsulation explosion-proof structure, exhibiting good moisture resistance and insulation properties, maintaining a stable resistance value even under high voltage and high temperature environments.

This series has passed UL1412 international safety certification and is widely used in power supplies and control systems with high requirements for stability and protection performance.
