FAQs
Install the 4P fixed-mount breaker in a compatible DC panel, connect conductors to the front terminals using appropriate terminal torque per the panel spec, and verify insulation between live parts. Confirm the device is correctly seated, the release mechanism engages reliably, and the wiring matches the 20 A rating and 500 V DC operating range to ensure proper protection.
Rated Current In is 20 A, rated operational voltage is 500 V DC, and rated insulation voltage Ui is 1000 V. It provides a rated impulse withstand voltage Uimp of 8 kV. Short-circuit performance is up to 36 kA (Ics/Icu) under specified conditions, with a rated uninterrupted current of 160 A, supporting reliable protection for DC feeders and drives.
The 4P XT2N DC MCCB with TM/TMD release is suitable for protective switching in DC distribution to protect drives and panels, particularly where front-terminal wiring and compact form-factor are beneficial. It offers robust short-circuit protection (Ics/Icu up to 36 kA) and 500 V DC capability, but ensure the continuous operating current and duty cycle align with your motor drive's load profile.
It complies with IEC 60947-2 standards and CE declarations, with RoHS compliance and REACH declarations. End-of-Life guidance, disassembly instructions, and an Environmental Product Declaration (EPD) option are available, along with recyclability data under EN45555, supporting sustainability and regulatory requirements.
With a mechanical durability rating of 25,000 cycles and a low power loss of 1.62 W per pole, the unit reduces wear, thermal stress, and cooling needs, lowering maintenance and energy costs. Its recyclability rating (55.7%) and disassembly guidance facilitate end-of-life recycling, supporting corporate sustainability targets and potentially lowering total cost of ownership over the product lifecycle.
