Progressive Industries Hardwire 50 Amp RV Surge Protector - W/Remote Display

Protect your 50-amp RV with the gold standard in electrical protection — the Progressive Industries EMS-HW50C Hardwired Electrical Management System. This is a full microprocessor-controlled EMS, not merely a surge protector. It continuously monitors your shore power and automatically cuts power to the RV the instant a dangerous condition is detected, then restores it automatically once power returns to safe levels.

What Sets the 50-Amp EMS-HW50C Apart

Compared to its 30-amp counterpart, the EMS-HW50C steps up to 5-mode surge protection covering all five possible surge paths on a 240V/50A system, with nearly double the joule capacity at 3,580 joules and 88,000 amps of surge current. For larger rigs running 50-amp service and more onboard electronics, that's a meaningful jump in protection.

Why Hardwired Beats Portable

Because it hardwires directly between your RV's AC inlet and electrical panel, the EMS-HW50C is always in place — there's nothing to forget at home and nothing exposed at the pedestal for someone to walk off with. Portable units sit out in the weather and only stop surges; they can't detect open grounds, reversed polarity, lost neutrals, or frequency faults. The EMS-HW50C monitors all of these conditions simultaneously and responds in under a nanosecond, every time you plug in.

Remote Digital Display

The included 14-foot remote display cable lets you mount the scrolling digital readout inside your RV, so you can monitor voltage, amperage, frequency, and fault codes at a glance without stepping outside to the unit.

Complete Protection Features

• High/low voltage protection — cuts power below 104V or above 132V, then auto-restores when safe
• 5-mode surge protection — covers L-N, L-N, L-G, L-L, and N-G; 3,580 joules / 88,000A / <1 nanosecond response
• Accidental 240V protection — blocks incorrect 240V connection; if detected while powered, shuts off instantly (displays voltage + E-3)
• Open ground protection — blocks power and displays E-2
• Reverse polarity protection — blocks power and displays E-1
• Lost/open neutral protection — blocks power entirely; display won't light
• AC frequency protection — shuts down if frequency deviates more than ±9 Hz from 60 Hz (E-7 or E-8)
• Surge fault indicator — E-10 alerts you if a surge has damaged the internal surge circuit
• Previous error indication — stores and displays the last fault code (PE prefix) for easy diagnosis; clears when power is disconnected
• Adjustable A/C compressor time delay — 136-second and 15-second settings prevent short-cycling
• Microprocessor controlled — manages all EMS functions and monitoring simultaneously
• Thermal protection — internal safeguards protect the unit in extreme conditions
• Field serviceable / modular design — individual components replace plug-and-play without removing the whole unit
