Category Specification Fisher Part Number 627-1217-29855 Description Trim & Plug Kit Assembly Applicable Valve Series Fisher ED, EDT, ES, EST, ET Series Eccentric Rotary Valves Trim Type Eccentric Rotary Plug Trim Plug Type Standard Eccentric Plug Flow Characteristic Standard (Approximately Equal Percentage) Primary Material Plug (Valve Ball): Hardened 17-4PH Stainless Steel Sleeve/Seat: Typically 17-4PH SS or 316 SS Hardness Plug is heat-treated (hardened) for enhanced wear and cavitation resistance. Seat Leakage Classification When assembled with a compatible seat, typically meets ANSI Class IV (0.01% of rated capacity) or better. Typical Service General service for liquids, gases, and steam. Ideal for applications requiring good shut-off and erosion resistance.

The Schneider LP1K09004BD contactor is a universal type suitable for both DC and AC loads, featuring the following core characteristics:

Basic Parameters

Coil Voltage: Supports various voltage types such as 24V DC, 220V/48V/110V/125V DC.

Contact Specifications: 4P (4 poles), with the number of normally open contacts varying according to the specific model (e.g., 4 normally open, 2 normally open, etc.).

Rated Current: 20A, suitable for medium load requirements.

Key Parameters Category Description / Value Product Line Eaton PKZM Series / Frame Size PKZM4 Rated Current (Iᵼ) 50 A (This is the frame size or the maximum setting current for the release). Rated Operational Current (Iₑ) - Setting Range Adjustable from 25 A to 50 A via a rotary dial. This allows it to be set to the full-load current of the specific motor being protected. Poles 3-Pole Rated Operational Voltage (Uₑ) 690 V AC, 50/60 Hz Rated Insulation Voltage (Uᵢ) 690 V AC Utilization Categories AC-3: Squirrel-cage motors (starting, switching off during running) AC-1: Non-inductive or slightly inductive loads Short-Circuit Protection Magnetic Trip (Instantaneous) • Setting: Typically fixed or adjustable depending on the model variant. For a standard PKZM4-50, the magnetic trip value is often fixed at 14 x Iₑ (e.g., 700A at the 50A setting). Always check the datasheet for the specific variant. Overload Protection Thermal Trip (Inverse Time) • Setting: Adjustable from 25 A to 50 A. • Trip Class: Class 10 (fast tripping characteristic, suitable for standard motor starting). Rated Service Short-Circuit Breaking Capacity (Ics) Typically 50 kA at 400V AC (according to IEC 60947-2). Rated Ultimate Short-Circuit Breaking Capacity (Icu) Typically 50 kA at 400V AC (according to IEC 60947-2). Control Circuit Function Manual ON/OFF switching with a toggle handle. Can be padlocked in the OFF position for safety (lock-out tag-out). Standards Compliance IEC/EN 60947-2 (Circuit-breakers) IEC/EN 60947-4-1 (Contactors and Motor-Starters) Connection Screw terminals. Auxiliary Contacts Available as an add-on module (e.g., PKZM0-XAU, PKZM0-XS1) that can be easily snapped onto the side of the breaker to provide signaling (e.g., trip indication). Compatible Contactors Designed for coordination with Eaton DIL series contactors (e.g., DILM) to form a coordinated motor starter combination.
