스린 SP11 (SP11) 접촉기

A Reliable Switch for Industrial Control Basic Information
브랜드 및 모델
It is an AC 접촉기 of the SP11 series produced by Shihlin Electric (Taiwan). It is often written as “SP11” in the market, and both notations are interchangeable.

제품 포지셔닝
It is a smallsized industrialgrade AC contactor, suitable for motor control and onoff control of circuits in general power systems.

기원
Original production in Taiwan; some versions sold in mainland China are domestically assembled. Core Specifications and Parameters

제품 특징 및 장점
1. Multiple Safety Certifications
It has passed international standard certifications such as GB 14048.4, IEC 6094741, UL 508, CSA, TÜV, 및 CE, ensuring safe use worldwide.

2. Flexible Voltage Adaptation
   It supports multiple control coil voltages (24V380V), adapting to the needs of power systems in different regions and facilitating global procurement and use.
3. Reliable Arc Suppression Design
   It adopts an automatic arc suppression structure to form a closed arcextinguishing chamber. It has a good arc suppression effect and zero arc flash distance, enhancing operational safety.

시작, 멈추다, and forwardreverse control of small and mediumsized threephase asynchronous motors (5.5kW 이하).
Used in conjunction with thermal overload relays (such as the THP series) to provide overload protection and form a complete motor starter.

2. Industrial Automation Equipment
   Power control for various production machinery and processing equipment.
   Onoff control of circuits for machine tools, 사출 성형 기계, 그리고 다른 장비.
3. 전력 시스템
   Circuit switching in power transmission and distribution control systems.
   Centralized control of lighting, 공기 조절, 그리고 다른 장비.
4. 기타 애플리케이션
   엘리베이터 제어 시스템.
   Control of pump equipment.
   Control of fans and other occasions requiring frequent startstop operations.

Model Description and Selection Key Points
표준 모델
SP11: 표준형, nonreversible contactor with 1NO auxiliary contact.
S2xP11: Reversible type (double contactor combination), used for forwardreverse control of motors.
SP11T: Integrated model with thermal overload protection function.

Key Parameters for Selection
1. 정격전류: Select based on the load current, ensuring it is ≥ the actual operating current.

3. 연락 유형: Select 1NO, 1NC, or combined type according to control requirements.
4. 운영 환경: 습기가 많은 곳에서는 사용을 피하세요, 신랄한, or hightemperature environments. 설치 및 유지 관리 권장 사항
1. 설치 방법
Guide rail mounting (HT35 standard) 또는 나사 고정 (M4 screw hole). The inclination of the mounting surface relative to the vertical plane should not exceed 5°.

2. 배선 참고 사항
   Main contacts are connected to the load circuit, and auxiliary contacts are connected to the control circuit.
   Ensure wiring is secure to avoid heat generation or malfunctions caused by loose connections.
3. 정기점검
   Clean the contact surface and remove oxide layers.
   Check if the coil connections are loose.
   Ensure the arcextinguishing chamber is undamaged to maintain good arc suppression performance.
