ZTC Type B Current Transformer For EV Charging

ZTC Type B Current Transformer For EV Charging

1. Full DC & AC Leakage Detection Compliance
Detects 6mA DC and 20/30mA AC residual currents — fully compliant with IEC 62752 and UL2231, making it ideal for EV charging safety.

2. Wide Operating Temperature – From -40°C to +105°C
Engineered for reliability in extreme environments, from freezing cold to high-heat industrial or outdoor conditions.

3. Fast Calibration & Built-in Self-Test Logic
Supports automated calibration (≥240ms) and self-test mode (≥60ms), with clear SCR output logic (DC 4.8V when fault detected), simplifying integration and diagnostics.

4. Low Power Consumption, High Precision
Consumes only 110mW, yet maintains accurate detection through calibration signal compensation — ideal for energy-conscious smart systems.

5. Clear Digital Output with Strong Drive Capability
SCR signal output delivers clear fault status (LOW 0V / HIGH 4.8V), with current drive capability up to 5mA, allowing direct interfacing with control systems.

6. Designed for Seamless Embedded Integration
Supports 5V ±0.25V supply, simple digital pin control logic, and standardized signal timing – making it plug-and-play friendly for most microcontrollers and safety modules.

  • Product Detail

Type B current transformers (CTs) are commonly used in charging piles/guns and energy-saving devices. These CTs are designed to accurately measure the current flowing through a conductor and provide a proportional output signal to an associated monitoring or control device.


Type B CTs are typically used for applications where the primary current is relatively constant, such as in charging piles or guns for electric vehicles, where the current is typically controlled to a set level during charging. Type B CTs have a high level of accuracy over a wide range of frequencies, making them suitable for use in a variety of applications.

Any detected leakage should be addressed promptly to prevent damage to the equipment or potential safety hazards.


Now, Xiamen ZTC Technology Co., Ltd has New Launch Type B CT For The Electrical Safety Module In EV Charging Application.


Behind Every Type B CT Is 20+ Years of R&D in Leakage Detection

Engineered for Safety. Optimized for EV Charging Systems.
