1. Usage description:
JZC2H-P (3TH3.) series intermediate relays are suitable for controlling contactors, relays, electromagnets, or transmitting control signals. There can be up to 8 pairs of auxiliary contacts. The coil control power supply can be alternating current (AC) or direct current (DC).  
The product meets the requirements of GB14048.5 and IEC60947-5-1 standards.  
The JZC2H-P series intermediate relay can be interchangeable with Siemens' 3TH3 intermediate relay.  
2. Structural features:
① The relay adopts an E-shaped iron core and a double break bridge contact system with a direct motion structure, ensuring reliable operation;  
② The relay action mechanism is flexible, easy to manually inspect, compact in structure design, and can prevent external debris and dust from falling into the active parts of the relay. The wiring terminals are covered with covers, and human hands cannot directly touch live parts, which provides high safety protection;  
③ The contact is a bridge double break structure, and the contact material is made of silver alloy with superior electrical performance, which has a long service life and good contact reliability. The arc extinguishing chamber is enclosed and equipped with flame-retardant materials to prevent the arc from spraying outwards, ensuring the safety of personnel and electrical appliances;  
④ Electromagnets work reliably, with low losses and noise, and have high mechanical strength.  
⑤ Easy to install, can be installed with screws or 35mm standard card rails.
