Why Choose the ESE15-315-BM?
| Advantage | Benefit for Your Application |
|---|---|
| ✅ 150kA @ 1500VDC | Interrupts extreme fault currents at the industry-leading 1500VDC level - headroom for 1000V/1500V-class EV fast chargers, BESS racks and PV-fed DC systems. |
| ✅ aR Semiconductor Protection | Partial-range back-up characteristic is coordinated with IGBT / SiC short-circuit withstand - protects expensive power modules in chargers, inverters and DC-DC stages. |
| ✅ Built-in Striker Indicator | Red blown-fuse pin enables visual checks and can drive auxiliary micro-switches for remote alarm and automatic shutdown logic. |
| ✅ Efficient 58W Power Loss | Only 58W dissipated at full 315A load - less heat build-up in sealed charging cabinets and battery boxes, lower cooling cost. |
| ✅ One Frame 100-500A | The entire BM series shares identical 180 × 51mm dimensions and Ø10.5mm terminals - change protection rating without redrawing the busbar or cut-out. |
| ✅ Certified, 3-Year Warranty | Designed to IEC 60269-4 with CE marking (UL 248 / ISO 8820 / GB/T 31465 referenced) and backed by a 3-year warranty for OEM projects. |

Frequently Asked Questions
Q1. What is the ESE15-315-BM used for?
A: It is a 315A / 1500VDC high-voltage DC fuse for EV fast chargers, energy storage systems, PDUs, DC-DC converters, inverter DC links, PV combiner circuits and industrial drives - anywhere a high-energy DC circuit needs short-circuit protection.
Q2. What does the "aR" characteristic mean?
A: aR is a partial-range back-up fuse class (IEC 60269). It clears only overloads above roughly 2× rated current and reacts extremely fast, making it ideal for protecting semiconductor devices (IGBT / SiC / diodes) that cannot tolerate long fault durations. It is normally paired with an upstream overcurrent device that handles lower overloads.
Q3. Why is the datasheet showing 150kA while the nameplate reads 170kA?
A: 150kA is the series guaranteed breaking capacity used across the ESE15-BM datasheet; the nameplate on this batch is marked with its tested 170kA class. Either way, the fuse safely interrupts the maximum prospective short-circuit current of typical 1500VDC installations. Contact us if your specification requires the exact certified figure.
Q4. How does the striker indicator work?
A: When the fuse element melts, a spring-loaded red pin extends from the striker cover. It provides a visual "blown" signal and can press an auxiliary micro-switch wired to your BMS / controller for remote alarm or contactor trip logic.
Q5. What is the difference between BM, BF and BL types?
A: They are terminal/shape variants of the same 1500VDC series. BM (this listing) uses flat tab terminals with Ø10.5mm bolt holes on a 148±1mm spacing in a 180 × 51mm frame; BF and BL differ in terminal form and overall length (see their dimension drawings, available on request). All cover 100-500A at 150kA.
Q6. How do I select the right rating and get certificates?
A: Size the continuous current with derating for ambient temperature and enclosure (typ. 0.7-0.8×), then verify I2t coordination with the protected device. IEC 60269-4 test reports and CE certificates are available on request; the product is covered by a 3-year warranty.
