⚡ Key Features

400V AC maximum continuous operating voltage (Uc) — remains permanently connected to the live supply; clamping only activates during overvoltage events.
MOV (Metal Oxide Varistor) clamping technology — responds in nanoseconds (< 25ns) to clamp transient overvoltages before they reach connected sensitive electronics.
Visual end-of-life indicator — green flag (healthy) turns red when the MOV has absorbed its rated energy and must be replaced; ensures protection level is always verified.
35mm DIN rail mounting — installs inside the main distribution board at the point of entry; protects the entire downstream installation in a single device.
Type 2 / Class II — installed at sub-distribution boards as secondary protection after a Type 1 at the main intake; protects equipment from switching transients and residual lightning energy.
Manufactured to IEC 61643-11 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified where applicable — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised AUSP023PN15 product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: What does the 15 kA breaking capacity on the AUSP023PN15 mean in practice?

A: Breaking capacity (15 kA) is the maximum prospective short-circuit current the AUSP023PN15 can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 15 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

Q: After a short-circuit trip on the AUSP023PN15, can it be reset and reused immediately?

A: After a short-circuit trip, do not immediately reset the AUSP023PN15. First, identify and clear the fault. Then inspect the device — if there is visible arc damage, melted insulation, or the handle does not reset smoothly, the device must be replaced. The 15 kA rated breaking capacity is not unlimited — it is the maximum fault current the device can interrupt safely for a defined number of operations (typically 1–3 at full Icu rating). After any significant fault, factor replacement into your maintenance budget.
