The Lovato 11B2504L00220C220 is a heavy-duty four-pole industrial power contactor designed for reliable switching of high-current electrical loads. Part of the established Lovato B250 contactor series, it is supplied with a factory-fitted mechanical latch for applications that require the contactor to remain in its operating position without continuous coil energisation.
This contactor features an electronically controlled 220–240 V AC/DC operating coil and an integrated Lovato G495 mechanical latch. The latch is released using a dedicated 220–240 V DC release coil, making the unit suitable for energy management, power distribution and industrial control systems requiring maintained switching.
With an IEC conventional thermal current rating of 350 A in AC-1 duty and four main power poles, the 11B2504L00220C220 provides dependable switching for resistive loads and high-current electrical circuits. Its robust construction and mechanically latched operation make it suitable for demanding industrial installations.
Mechanically latched contactors remain in their selected operating position after the closing control signal has been removed. This reduces continuous coil energy consumption and helps maintain the switching state during temporary control-voltage interruptions.
The Lovato 11B2504L00220C220 uses separate electrical commands for closing and releasing the contactor. Its 220–240 V AC/DC operating coil closes the main contacts, while the dedicated 220–240 V DC release coil disengages the mechanical latch when the circuit must be opened.

It is used for mechanically maintained switching of high-current electrical loads in industrial power distribution, automation and energy-management systems.
The contactor has an IEC conventional thermal current rating of 350 A in AC-1 duty.
The contactor operating coil is designed for a control voltage of 220–240 V AC or DC.
The factory-fitted G495 mechanical latch is electrically released using a dedicated 220–240 V DC release coil.
No. The mechanical latch holds the contactor in its operating position after the closing signal is removed, reducing continuous control-coil power consumption.
Lovato mechanically latched B250 contactors are widely used by electrical engineers, panel builders and industrial system designers for dependable maintained switching of high-current power circuits.{ "@context": "https://schema.org/", "@type": "Product", "name": "Lovato 11B2504L00220C220 Four-Pole Mechanically Latched Contactor 350 A", "sku": "11B2504L00220C220", "mpn": "11B2504L00220C220", "brand": { "@type": "Brand", "name": "Lovato Electric" }, "category": "Mechanically Latched Power Contactors", "description": "Lovato 11B2504L00220C220 four-pole industrial contactor with a 350 A AC-1 thermal current rating, 220–240 V AC/DC operating coil and factory-fitted G495 mechanical latch with a 220–240 V DC release coil.", "gtin13": "8013975048047", "additionalProperty": [ { "@type": "PropertyValue", "name": "Thermal current", "value": "350 A AC-1" }, { "@type": "PropertyValue", "name": "Operating coil voltage", "value": "220–240 V AC/DC" }, { "@type": "PropertyValue", "name": "Latch release voltage", "value": "220–240 V DC" }, { "@type": "PropertyValue", "name": "Number of poles", "value": "4" }, { "@type": "PropertyValue", "name": "Mechanical latch", "value": "Lovato G495, factory fitted" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the Lovato 11B2504L00220C220 used for?", "acceptedAnswer": { "@type": "Answer", "text": "It is used for mechanically maintained switching of high-current electrical loads in industrial power distribution, automation and energy-management systems." } }, { "@type": "Question", "name": "What is the current rating of this contactor?", "acceptedAnswer": { "@type": "Answer", "text": "The contactor has an IEC conventional thermal current rating of 350 A in AC-1 duty." } }, { "@type": "Question", "name": "What voltage does the main operating coil require?", "acceptedAnswer": { "@type": "Answer", "text": "The contactor operating coil is designed for a control voltage of 220–240 V AC or DC." } }, { "@type": "Question", "name": "How is the mechanical latch released?", "acceptedAnswer": { "@type": "Answer", "text": "The factory-fitted G495 mechanical latch is electrically released using a dedicated 220–240 V DC release coil." } }, { "@type": "Question", "name": "Does the contactor require continuous coil power?", "acceptedAnswer": { "@type": "Answer", "text": "No. The mechanical latch holds the contactor in its operating position after the closing signal is removed, reducing continuous control-coil power consumption." } } ] }
