HZ5371X 1000A Primary Current Injector Price

HZ5371X 1000A Primary Current Injector is a testing device independently developed by our company. It incorporates the advantages of similar domestic and international products and adopts CNC technology, providing strong anti-interference capability. Compared to previous generations, it offers higher output power, smaller size, and lighter weight, thanks to the use of a low-power, high-capacity autotransformer and a converter made with a high-permeability iron core.

This equipment is primarily used for testing thermal relays, motor protectors, contactors, circuit breakers, air switches, switchgear, and protection panels, as well as for testing the transformation ratio of primary busbar protection and various current transformers. It is widely used in R&D, production, and electrical testing sites across industries such as power, railway, petrochemical, metallurgy, and mining.

II. Main Features & Functions

1. Functions

Can output 0–1000 A current continuously for extended periods

Synchronizes with test equipment to measure operating time

Automatically identifies normally open (NO) and normally closed (NC) contacts

Determines test timing based on current presence in the absence of contact reconnection

Features a pre-current adjustment function, allowing current presets even when output is disconnected

Multiple testers can be connected in series to improve work efficiency

2. Characteristics

Aesthetically designed with PVC panel

Direct display of primary and secondary current values and calculated transformation ratio for easy observation and recording

Displays 0–360° phase angle for primary and secondary currents, plus polarity indication

Measurement accuracy: Class 0.2

High power, compact size, and strong load capacity

Small and lightweight, with a volume only 30%–70% of similar products, making it highly portable
