Product Description

HYCA Type AC DC Leakage Current Sensor

The HYCA type AC DC leakage current sensor is an all-current sensitive residual current sensor specifically developed for EV-charging. Charging of electric vehicles at a standard wall socket or a wall box requires protection devices against DC fault currents to avoid electric shock. Standard Type A residual current circuit-breakers (RCCBs) are unable to identify and deactivate DC fault currents, making the HYCA sensor an essential component for safety compliance.

Frequently Asked Questions

Q1: What is the primary function of the HYCA leakage current sensor?
A1: It is designed to detect both AC and DC leakage currents in EV charging systems, providing protection against electric shocks where standard Type A RCCBs might fail.
Q2: Why is 6mA DC detection important for EV charging?
A2: According to IEC standards, DC leakage above 6mA can saturate a Type A RCCB, preventing it from tripping during an AC fault. This sensor ensures safety by identifying these DC faults.
Q3: Is the sensor suitable for outdoor charging piles?
A3: Yes, with an IP65 rating and a wide working temperature range of -40ºC to +105ºC, it is designed for both indoor and harsh outdoor environments.
Q4: Does the HYCA sensor support self-testing?
A4: Yes, the sensor includes integrated self-monitoring and test functions to ensure ongoing operational reliability.
Q5: What standards does this sensor comply with?
A5: It meets major international standards including IEC 62752, IEC 62955, and UL 2231-2, ensuring global compatibility for EVSE manufacturers.
Q6: What is the expected lifespan of the sensor?
A6: The HYCA series is designed with a service life of 20 years or more, making it a durable choice for long-term infrastructure.
