JUNW D165T/D265T Digital-triggered Pole Circuit Breaker

D165T/D265T Pole-Mounted Circuit Breakers
1.Product Basics & Compliance
The D165T and D265T are 4-pole (3 protected poles) air-insulated disconnectors with a metal baffle chamber for arc quenching, fully complying with the HN 63-S-11 standard. Housed in a wind and rain-resistant glass fiber reinforced polyester enclosure, they are purpose-built for pole-mounted outdoor installation.
2.Core Electrical Parameters
Both models operate at a 440V rated voltage with tailored performance:
•D165T: 165A rated current, 4000A breaking capacity, 6800A making capacity, 1 output, compatible with 25/70 mm² cables.
•D265T: 265A rated current, 6400A breaking capacity, 11700A making capacity, 2 outputs, compatible with 50/150 mm² cables.
They boast strong dielectric performance: 20kV impulse/ground withstand, 10kV at 50Hz, and 4kV inter-pole withstand.
3.Smart Protection & Control
A separate excitation trip unit enables remote tripping (e.g., triggered by a fire room button) for emergency control. During opening, it links the transformer neutral line to the busbar; when closed, a dedicated spark gap limits the BT neutral point voltage rise relative to busbar grounding, supporting applications exceeding 10kV.
4.Operational Reliability
Featuring manual control, these breakers deliver stable long-term performance for outdoor power distribution, with flexible current and capacity options to meet diverse grid connection demands.
