QS12-S Connector Cable 250A Male And Female Battery Plug Wire Anti-ignition

Intrinsic safety design limits spark energy below minimum ignition thresholds , eliminating arcing during connection/disconnection

Pre-charge circuit reduces voltage differential before full contact, preventing electrical sparks in high-voltage systems

Polarity-locked housing prevents reverse connection, avoiding short-circuit-induced ignition risks

250A continuous current rating, 320A peak current capacity  for high-power applications

4AWG (21.1mm²) stranded copper wire minimizes voltage drop ( 250A) and power loss

Gold-plated brass contacts (≥3μm thickness) ensure ultra-low contact resistance (≤0.2mΩ)

PA (nylon) housing with UL94 V-0 flame-retardant rating , self-extinguishing in fire exposure

Wide operating temperature range: -30℃ to 150℃ , adapting to extreme environmental conditions

Sealed rubber gasket provides IP65-level dust/water resistance , suitable for outdoor/harsh environments

Shock-resistant construction withstands vibration (15g, 10-2000Hz) and mechanical impact

Textured grip with embossed ridges enables easy plug/unplug even with gloves

Audible locking mechanism confirms secure mating, preventing accidental disconnection

Color-coded housing (male: black, female: gray)  simplifies identification and installation
