KJD12 Electromagnetic Switch (Model KJD12) - Key function: Magnetic pressure switch for on/off control in electrical circuits. - Electrical rating: 12 A at 220 V AC — suitable for loads up to 12 amps on 220 V supply circuits. - Protection: Waterproof and explosion-proof construction to reduce risk from moisture and hazardous atmospheres. - Reliability: Magnetic pressure actuation provides consistent switching performance for control and safety applications. - Compatibility: Intended for systems and control circuits that require a 12A/220V magnetic pressure switch and where waterproof/explosion-proof components are needed. KJD18 Three-Phase Start Switch (Model KJD18) - Part of the same product family for three-phase motor starting and control applications. - Designed to complement the KJD12 series where three-phase starting devices are required. Why customers choose these switches - Safety in harsh environments: Waterproof and explosion-proof design protects equipment and personnel where moisture or flammable atmospheres are present. - Right fit for 220 V control circuits: The KJD12’s 12A/220V rating aligns with common single-phase control loads; the KJD18 provides the three-phase start option for motor control. - Simple system integration: Use in control panels and circuits that require magnetic pressure switching and robust environmental protection. Practical applications - Pump and valve control in outdoor or wet locations where waterproof, explosion-proof switching is required. - Motor starting and control for three-phase equipment (use KJD18) in industrial settings such as manufacturing, processing, or HVAC systems. - Control and safety circuits in potentially hazardous areas such as chemical plants, oil and gas facilities, or mining operations where explosion-proof protection is necessary. Technical highlights (summary) - Model: KJD12 — electromagnetic (magnetic pressure) switch - Rating: 12 A / 220 V - Protection: Waterproof and explosion-proof - Related model: KJD18 — three-phase start switch in the same product line Note: Select the KJD12 for single-phase control circuits at 12A/220V with waterproof and explosion-proof requirements; choose the KJD18 when a three-phase start switch is needed in the same application environment.
