deta Description: CE-certified RDJZ-VAPS intelligent voltage & current protector from PEOPLE ELECTRIC delivers 0.1s fast-acting overvoltage, undervoltage and overcurrent protection for 220V 50/60Hz systems. Fully configurable, DIN rail mounted, ideal for residential, commercial, municipal and agricultural applications across emerging markets.
Across residential, commercial, industrial and agricultural electrical systems, unstable grid voltage and overcurrent faults are among the most common causes of equipment damage, unplanned downtime and even electrical fire hazards. In emerging markets across the Middle East, Africa and Southeast Asia — where grid quality can be inconsistent and voltage surges, sags or brownouts are frequent — the cost of unprotected circuits runs into millions of dollars annually in premature equipment replacement, lost productivity and safety liabilities.
Traditional fuses and miniature circuit breakers only provide basic overcurrent protection. They cannot actively monitor voltage levels, nor can they respond to overvoltage or undervoltage conditions before permanent damage occurs to sensitive electronics, motors or heating equipment.
For comprehensive, configurable and ultra-fast electrical protection on 220V AC circuits, the RDJZ-VAPS Intelligent Over/Under-Voltage & Current-Limiting Protector from PEOPLE ELECTRIC delivers a complete, cost-effective solution that extends equipment lifespan and reduces operational risk.
1. How the RDJZ-VAPS Solves Common Electrical Protection Gaps
The RDJZ-VAPS is an all-in-one intelligent protection device that continuously monitors both voltage and current on the supply side, and automatically disconnects the load when parameters fall outside configured safe ranges. Unlike basic protection components, it provides active, adjustable and fast-acting safeguarding for all downstream valuable equipment.
It addresses three of the biggest failure modes in low-voltage electrical systems:
• Overvoltage surges from grid switching, lightning induction or generator anomalies
• Undervoltage brownouts that cause motors to stall, overheat and burn out
• Overcurrent faults from short circuits, overloads or equipment failure
2. Core Features & Functional Benefits
Every feature of the RDJZ-VAPS is engineered for reliability, flexibility and ease of use in real-world installations.
☑Real-Time LED Status Display
The front-facing LED display shows live grid voltage and current values, allowing installers and operators to verify circuit status at a glance — no additional metering equipment required. Four dedicated indicator lights clearly show overvoltage (>V), undervoltage (<V), overcurrent (>A) and normal power (POWER) states for immediate visual diagnostics.
☑Fully Configurable Protection Parameters
All protection thresholds and timing settings are adjustable on-site via the built-in configuration menu, so the device can be precisely tuned to each application’s specific requirements instead of relying on one-size-fits-all factory defaults.
Configurable parameters include:
• Power-on delay: 1s – 999s
• Recovery delay: 1s – 999s
• Overvoltage threshold: 230V – 300V (0.1V step)
• Undervoltage threshold: 140V – 210V (0.1V step)
• Voltage trip time: 0.1s – 10.0s
• Overcurrent limit: 1.0A – 63A (0.1A step)
• Current trip time: 0.1s – 10.0s
The device also supports one-touch factory reset for fast reconfiguration or commissioning.
☑0.1s Ultra-Fast Rapid Disconnection
When voltage or current exceeds set thresholds, the RDJZ-VAPS enters rapid disconnection mode and cuts off the load within 0.1 seconds. This ultra-fast response shields sensitive electronic equipment, motor windings and heating elements from even transient anomalies that would cause permanent damage with slower protection devices.
☑Selectable Automatic / Manual Reset
Users can select between automatic self-recovery and manual reset mode:
Automatic mode: Restores power automatically once voltage and current return to normal ranges, minimizing downtime without on-site manual intervention — ideal for remote or unmanned sites.
Manual mode: Requires manual reset before re-energization, for applications where safety verification is required before power restoration.
☑Setup Lock Password Protection
A configurable setup password prevents unauthorized or accidental changes to protection settings, ensuring consistent and tamper-proof protection in public buildings, commercial facilities and rental properties.

6. Sizing & Installation Guidance
Selection Tips
1. Calculate the maximum continuous load current of your circuit.
2. Select a rated current model (40A / 63A / 80A / 100A) with appropriate headroom above normal operating current.
3. Set overvoltage and undervoltage thresholds based on local grid standards and equipment sensitivity.
4. Adjust time delays to avoid nuisance tripping from normal transient grid fluctuations.
5. Select automatic or manual reset mode based on site access and safety requirements.
