Product Overview
BGE1.5 is a SEW-Eurodrive brake rectifier built for fast brake release in industrial electromagnetic brake systems. It uses electronic switching and an integrated varistor for overvoltage protection. The module measures roughly 36 × 27 × 33.5 mm and weighs only 0.08 kg. Its red housing fits inside motor terminal boxes. Part number 8253854 identifies this exact unit. Engineers choose it for reliable brake timing and longer brake life.

Oiltech Controls’s Insight
Brake timing affects cycle time and brake wear. The BGE1.5 cuts release delay with electronic switching. The integrated varistor protects the coil from voltage spikes. We see this rectifier in conveyor and hoist retrofits. Its small red body fits tight terminal boxes. Check coil voltage and holding current before ordering. Our team verifies each unit before shipment.
FAQ
Q: Can I replace an older rectifier with the BGE1.5?
A: Often yes. Check coil voltage (150–500 V AC) and holding current (≤1.5 A). Confirm the mounting space fits 36 × 27 × 33.5 mm. Share your old part number with us for cross-check.
Q: What does IP10 protection mean for my installation?
A: IP10 blocks solid objects over 50 mm. It does not resist water. Mount it inside a motor terminal box or dry cabinet. Avoid washdown areas.
Q: How do I know if the varistor has failed?
A: A failed varistor often shows cracks or burn marks. The brake may release slowly or not at all. Measure coil voltage and compare with the input. Replace the rectifier if voltage drops under load.
Q: Does the BGE1.5 work with both AC and DC brake coils?
A: It is a one-way rectifier for AC input. It feeds DC to the brake coil. Use it only with AC-supplied brake coils rated 150–500 V. Do not connect DC supply to the input.
Q: What is the warranty and lead time?
A: Every BGE1.5 comes with a 12-month warranty. In-stock items ship in 24–28 hours via FedEx, UPS, DHL. Ask info@oiltechcontrols.com or message +86 158 8020 0923 on WhatsApp for stock status.
